WINDLASS AND CONNECTION.

SPECIFICATION forming part of Letters Patent No. 598,166, dated February1, 1898.

Application filed June 24,1897.

To all whom it may concern Be it known that HARLIN J. TRACY, residing atSalamanca, in the county of Cattaraugus and State of New York, haveinvented certain new and useful Improvements in VVindlasses andConnections, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to windlasses for drawing or straining surfacelines and the construction of such a Windlass with'the pullwheel usedfor drawing such lines in pumping oil-wells, 85c.

As shown in the patent of Lufkin, No. 539,746, dated May 21, 1895, alarge wheel is used for driving the pumps of a number of oil-wells fromone engine or motor. This large wheel or disk is called the pull-wheel,and this pull-wheel is generally mounted on a solid foundation only alittle above the ground, and the hub on which the wheel oscillatesextends a little above the flat face of the wheel. Quite a number ofcables are generally attached to the wheel and extend in variousdirections,- and when the wheel is rocked back and forth all thesecables are drawn and loosened alternately, and, as will be readilyunderstood, each cable may work a pump some distance away. It isnecessary that all the cables should be drawn taut or on the pull-wheel.When a cable breaks or is loosened for repairs or other purposes, thepull-wheel neednot be stopped. The wheel may go on operating all theother cables until a convenient time for stoppage for the attachment ofthe broken cable. \Vhen the cable is again attached, it must be drawn tothe proper tension.

To enable each and all the cables to be properly strained is the objectof my invention.

Figure 1 is a partial elevation and partial section of a pull-wheel withmy Windlass attached. Fig. 2 is a perspective View showing the mainparts of my invention ready for adjustment on the pull-wheel. Fig. 3 isa perspective View showing the machine in operative position. Fig. 4 isan end view of c'levis or pulley. Fig. 5 is a side view of clevis orpulley. Fig. 6 is an elevation of the brace.

port or anchorage B in any usual manner and has a number of holes nearits rim. A metal ring, collar, or sleeve 1 is the cent-er of my deviceand passes overor around the hub H of the pull-wheels A frame 2 ishinged or pivoted to a base-piece b, which is swiveled to collar 1 bypintle c. The base-piece b is pivotally united to the frame 2, as bypivots d, so that the frame can turn down or be raised up. This framehas two side pieces 4 4, and the frame forms or supports the bearings ofthe Windlass-drum 5 and of the crank-"shaft or'counter-shaft 6. TheWindlass-drum has a large driving-gear 7 firm] y connected, and thecrank-shaft or counter-shaft has a pinion 8 engaging this large gear.The crank 9, outside the frame, serves to turn the'countershaft andthereby the large gear and the winding-drum. If the crank be six timesas long as the diameter of the pinion and the drum be six times smallerthan the large wheel 7, then a given power at the crank should exertthirty-sixtimes as much at the winding-drum, and these or other suitableproportions may be employed.

The winding-drum has a cable 10 connected therewith, which cable may beconnected to any one of the cables driven by the pullwheel,so as toapply the proper strain thereon.

As the ring 1 may be turned on the hub of the pull-wheel, moving andreplacing bolts 6, as shown in the drawings, or by other suitableadjustment, the frame and its windingdrum may be made to face in anydirection. The frame is held upright against any pull on the indlass bythe forked brace-rod 12,which has one arm of its fork connected by acrosspiece 30 to each side bar of the frame. The brace-rod proper is intwo parts 12 and 13 and connected by a turnbuckle 14, engaging right andleft threads. The lower or outer part of the brace has a bolt 15,coupledthereto by loop-coupling, and this bolt 15 may pass through anyone of the holes near the rim of the pull-wheel and be secured by a nutbelow the wheel. It will be seen that this affords a very strong and .atthe same time flexible attachment or brace by which the frame 2 may beheld in upright position, and that its inclination may be adjusted bythe turnbuckle.

Looped to the collar or base of the frame there is a derrick-arm 2O. Atthe outer end of this arm there is a clevis 21, having a socket 22, inwhich the end of the derrickconnected to its inner end. This eyebolt canbe secured in any of the holes at the edge 7 of the pull-Wheel nearlyopposite the brace 12,

and in this way the derrick-arm will be held, with the clevis turned inalmost any direction, as the looped coupling of brace 24 and thesocket'on the clevis permit the clevis to be moved about the derrick-armas a center and attached at any suitable angle to present the pulley inconvenient position to draw to advantage.

When in use, the Windlass can be secured and braced, substantially asindicated in Fig. 1. When not in use, the derrick-arm may be turned intoupright position by detaching eyebolt 25, and the derrick-arm can thenbe tied back against the frame, or by detaching the brace both the frameand derrick may be turned down on the pull-wheel as nearly as wheel 7Will permit. Thus the Windlass may be gotten pretty well out of the waywithout removal from the pull-Wheel and can be adjusted to any needfulposition and held with great firmness on the wheel.

It will be understood that changes Within the scope of the claims maybe. made without departing from my invention.

I claim- 1. The combination with the pull-wheel at a centralpumping-station having holes near its edge of a base adj ustablyattached to said Wheel, a Windlass-frame pivoted to said base, and aWindlass thereon, and a brace extendsaid brace in one of the holes inthe wheel,

substantially as described.

2. The horizontal pull-wheel, the Windlass swiveled centrally of saidwheel and having a brace extending to near the wheel-rim, thederrick-arm extending from the base of the Windlass in oppositedirection from the'brace, and a link braced by the derrick-arm andconnected to the wheel-rim, and the cable passing over a support on thelink and so to the windlas's, all combined substantially as described.

3. In a cable-straining device for attachment to pull-wheels, theWindlass and its supports constructed for connection to the hub, thederrick-arm pivotally connected to the Windlass-base, a clevis at theouter end thereof, the brace-rod loosely connected to said clevis at oneside of the derrick-arm, the sheave in the clevis at the other side ofsaid arm, and a bolt loosely connected to the clevisbrace and extendinginto one of the holes in the pull-wheel, all combined substantially asdescribed.

4. In a cable-straining device, the base or central support, theWindlass havingits frame pivoted thereto, the forked brace pivotallyconnected near the top of said frame and provided with a turnbuckle andattaching-bolt, a derrick-arm pivoted to the Windlass-support, and aclevis at its outer end, with a brace loosely connected thereto and asheave in said clevis, all combined substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
